I really like this books. They use simple but common German, and they translate some words for you, but not all of them, leaving you room to translate them yourself by context :), not the best literature, but entertaining "fun-sized" stories that somehow stick to your head! (And pretty cheap too). http://www.amazon.com/s/ref=nb_sb_noss_1?url=search-alias%3Daps=die+dritte+hand

Here I found often answers to questions regarding German http://www.canoo.net/index_en.html

Deutsche Welle has some excellent materials. Also check out what the Goethe Institut has to offer.
